摘要： A node (100) for a communications network having a control plane distributed across multiple nodes, the node having a controller (20) arranged to run protocols of the control plane and an event logger (10) for logging events in the operation of the control plane protocols at the node. A local timing reference (30) in the node is synchronised to a common network clock, and an interface is provided for the event logger to communicate with an external log server at a different location. The event logger is arranged to use the local timing reference to determine a time for each logged event and to send an indication to the external log server of the logged events and their times. By timing events based on a common network clock, the log server can then determine a relative timing of events at different nodes more accurately, and thus facilitate tracing of events through the network.
摘要翻译：一种用于具有分布在多个节点上的控制平面的通信网络的节点（100），所述节点具有布置成运行所述控制平面协议的控制器（20）和用于在所述控制的操作中记录事件的事件记录器（10）节点上的平面协议。节点中的本地定时参考（30）与公共网络时钟同步，并且提供用于事件记录器与不同位置处的外部日志服务器通信的接口。事件记录器被安排为使用本地时序参考来确定每个记录的事件的时间，并向外部日志服务器发送记录事件及其时间的指示。通过基于公共网络时钟定时事件，日志服务器然后可以更准确地确定不同节点处的事件的相对定时，从而便于通过网络跟踪事件。

摘要： A method of operating a control plane having a centralised network management system (10), control domain servers (20) and a plurality of forwarding elements (30), for controlling respective network entities (L2), and grouped into control domains (21, 22, 23). Each domain has a control domain server. Automatic checking for inconsistencies (110, 115, 210, 310, 320, 450) between the records held at the different parts of the control plane, involves comparing checklists of the records of the circuits stored at the different parts of the control plane. If an inconsistency is found, there is automatic updating (120, 220, 230, 460) of the records using a copy sent from another of the parts of the control plane. The checklists can avoid the need to forwarding entire copies.

摘要： A connection - oriented network (5) has a working path (10) and a segment recovery path (12) for a segment (11) of the working path (10). The working path (10) has a branch node (N2) at an end of the segment where the segment recovery path (12) connects to the working path. The branch node is not located at an end node (N1, N7) of the working path. Control plane signalling is received (202) at an end node (N1, N5) of the working path (10) from a node along the working path, indicating that a failure has occurred along the working path. The end node (N1, N7) determines (203), from the received control plane signalling, if the failure has occurred outside the segment (11) of the working path. When it is determined that the failure has occurred outside the segment (11) of the working path, notifying (204) the branch node (N2, N5). The notification is an instruction not to reroute to the segment recovery path.

摘要： A network element for a communications network having decoupled control and data planes may be in either a first state, the control plane and data plane are configured to interact, whereas, in the second state, the network element suppresses a control message for the data plane such that the configuration of the data plane is preserved. Accordingly, the network element may be in a second state when the data plane is undergoing maintenance such that there is no interaction between the control and data planes.

摘要： A method for setting up a new path for carrying traffic between border nodes of a client communications network through a server communications network. The method comprises, at a border node of the client communications network: receiving a request for reservation of resources from a first client node of the client communications network; determining that the border node does not have a path for carrying traffic through the server communications network having sufficient resources to meet the request; and, in response, initiating set up of a new path for carrying traffic between border nodes of the client communications network through the server communications network.

摘要： The present invention provides a method for enabling Segment Routing in a multi-domain network comprising a client network domain and a server network domain,where the client network domain is a packet network domain and the server network domain is a connected-oriented network domain. The method comprises assigning a network segment identifier to each of one or more potential paths through the server network domain between a pair of overlay network nodes in the client network domain, wherein the one or more potential paths are not pre-configured and the or each network segment identifier is suitable for inclusion in one or more data packets to indicate to at least one of the pair of overlay network nodes a preselected network segment routing for the one or more data packets. The present invention further provides a method for routing data packets in the multi-domain network. The method, in an overlay network node in the client network domain,comprises receiving one or more data packets, and retrieving a network segment identifier included in at least one of the one or more data packets. The method further comprises determining that the network segment identifier indicates that the one or more data packets should be routed over a pre-selected potential path through the server network domain,and,based on the determining, triggering the server network domain to configure the pre-selected potential path through the server network domain.

摘要： A method and a network node for managing allocation of network resources in restoration of traffic in a connection oriented network are disclosed. The method comprises restoring (104) a first traffic from a first path on an alternative path if the first path is affected by a first failure (102) and assigning (106) a reserved status to resources of the first path no longer used for carrying the first traffic. If a second path is affected by a second failure the method comprises restoring (114) a second traffic from the second path, wherein the restoration of the second traffic does not use the resources having the reserved status.
